4 Percent Overdrive Lightweight Crankshaft Pulley For 02-06 Mini Cooper Hatchback 05-08 Convertiable M7 Speed
SKU #: MSP-53-3M7101-4-GJSC
Manufacturer Part #: 53-3M7101-4-GJSC
The M7 Speed 4 percent oversize - speed increasing crankshaft pulley will add power, acceleration and performance to your MINI. Speeding up your supercharger safely adds low end boost and torque which gets your MINI Cooper going.
Weighing in at a scant 13 ounces, (an amazing 88.5 percent less than factory) the lightweight M7 Speed 4 percent Crank Pulley reduces crankshaft rotational mass which equals additional increased horsepower, torque and throttle response.
This beautiful design is a result of advanced computer modeling and high precision CNC machining. Made in the USA from billet 6061-T6 aerospace grade aluminum alloy and finished with a deep black anodized coating and laser etching.
The Micro V-Belt grooves are machined to exacting SAE J1459 specifications for minimum belt slippage at maximum boost. Use this in combination with the M7 Speed 16 percent Supercharger Technology Pulley for maximum performance and boost yourself to the next level of MINI tuning and performance.
From the factory, the MINI suffers from no positive drive key on the crankshaft snout to drive the lower pulley. The factory pulley is press fit onto the crank. All aftermarket pulleys are slip fit at best and rely on the bolt to provide adequate clamp force to prevent the pulley from slipping.
The M7 Speed crank pulley is engineered with an interference fit onto the crankshaft eliminating pulley slippage on the crankshaft.
Simple to install. Heat the pulley to 275/300oF (135/150oC) in your kitchen oven or using a small propane torch and heat gun and the pulley will drop straight onto the crank.
When it cools it will be super tight onto the crank. Finish the installation with the supplied ARP bolt and precision flat washer and presto...more power, more reliability and more overall performance for your supercharged MINI Cooper.
Made in the USA
Fitment Notes :A larger 4 percent oversize speed increasing crank pulley will add just that little extra added supercharger boost and performance. This beautiful design is a result of advanced computer modeling and high precision CNC machining.
Made in the USA from billet 6061-T6 aerospace grade aluminum alloy with a deep black anodize coating, the M7 Speed 4 percent oversize - speed increasing pulley will provide a lifetime of reliable use.
Weighing in at just 13 ounces and supplied with a brand new high strength ARP bolt and precision ground flat washer, the M7 Speed 4 percent crank pulley is best in class.
Each M7 Speed product is Engineered....Tested....and Proven to Perform!
